There was no immediate comment from Ukraine. Russia and Ukraine accuse each other of war crimes. Both deny each other's allegations. There was no immediate comment from the WHO.

The accusation was made by Russian Foreign Ministry spokeswoman Maria Zakharova who told reporters that Ukrainian forces had repeatedly targeted medical facilities and doctors in four Ukrainian regions which Moscow says it has annexed.

Zakharova listed the dates and locations of the attacks in recent months and said the same information had been provided to the WHO which she said had done nothing with the data.

"Real doctors are dying from shelling by Kyiv with weapons supplied by the West," Zakharova said.

She said that the West - and the Western media - had ignored any crimes carried out by Ukraine and only wanted to criticise Russia.
